What You'll Learn

ES12 launch monitor accuracy
The ES12 is a portable launch monitor from Ernest Sports that provides golfers with robust swing feedback at a fraction of the cost of its industrial counterparts. It is a pocket-sized launch monitor with a dimension of 5.3″ (h) x 3.0″ (w) x 1.6″ (d). It is easy to set up and use. You just place the unit 12-14 inches over and 12-14 inches ahead of where you are hitting. There are only two buttons: Power and Club Selection. You just select the club on the device before you start hitting.
The ES12 uses Doppler radar technology to measure ball speed accurately and calculate distance. It does not measure launch and spin, but it does react to various launch and spin conditions. The results are displayed on the LCD screen immediately after playing a shot. The ES12 can also be operated with a free app that is compatible with iOS and Android devices and can be connected via Bluetooth. The app tracks and stores each range session, enabling further analysis, and data can be converted into Excel format.
Reviews of the ES12 launch monitor's accuracy are mixed. Some users have found it to be surprisingly accurate, with one user stating that they took it to the range several times during the review process to confirm the distances. They scoped the flags with their laser and then hit, and while they couldn't say how exact it was for longer shots, they were impressed with the data it provided for shorter shots. Another user stated that they knew their yardages with their clubs and that each club was pretty much dead on. They also found the ES12 to be accurate for short shots, with the unit providing almost exact carry distances for pitches and wedges.
However, other users have expressed skepticism about the accuracy of the distances provided by the ES12. One user pointed out that the ES12 does not directly "track" distance but instead measures ball speed and club used to calculate distance. They suggested that the distances provided by the device might not be reliable. Another user mentioned that they would be interested in comparing the ES12 back-to-back with a Trackman for accuracy, as they had noticed the ES12 throwing off the odd big reading.
Overall, while some users have found the ES12 launch monitor to be accurate, others have questioned the reliability of the distances it provides, particularly since it does not measure launch and spin rates.
